When vegetable farmers harvest crops, they often rely on postharvest washing to reduce any foodborne pathogens, but a new University of Georgia study shows promise in reducing these pathogens – as well as lowering labor costs— by applying sanitizers to produce while it is still in the fields.
Current poultry food safety guidelines for Salmonella, the leading cause of foodborne illness outbreaks, are inadequate. A new study conducted by Thomas Oscar, USDA Agricultural Research Service, “Salmonella prevalence alone is not a good indicator of poultry food safety,” published in Risk Analysis, explores additional factors that must be considered in order to identify poultry products that are truly safe for human consumption.
Researchers have discovered that bacteria such as salmonella and E.coli have a backdoor to capitalize on our reliance on leafy greens for a healthy diet. Wild strains of salmonella are delivering foodborne illnesses by circumventing a plant’s immune defense system to get into the leaves of lettuce.
Beneficial bacteria in reused poultry litter can reduce Salmonella levels
Researchers found that co-administering dephostatin and colistin in mice with a lethal Salmonella infection significantly prolonged animal survival and used a lower concentration of colistin than is normally required for treatment, thereby reducing its toxic effect.
Researchers from Cornell and the Mars Global Food Safety Center can complete whole-genome sequencing to determine salmonella serotypes in two hours and the whole identification process within eight hours.
Study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the body
Nerves in the gut prevent Salmonella infection by shutting the cellular gates that allow bacteria to invade the intestine and spread beyond it
As a second line of defense, gut neurons help avert Salmonella invasion by maintaining the levels of key protective microbes in the gut
Findings reveal prominent role for nervous system in infection protection and regulation of immunity
